Who’s Building that Data Center?

Hackaday reports on the Powered By Who project, which is mapping the country's rapid expansion of AI data centers. The tracker has identified over two thousand data centers across the United States, ranging from early proposals to fully operational sites.

That concentration raises serious questions about power consumption, water use, and emissions in those regions — plus who benefits from the development. Engineers are now exploring creative solutions to manage the massive cooling loads, from innovative DC distribution systems to underwater and even space-based data centers.
